Legacy Service Life Extension Program (SLEP) Structures

Abstract

F-16 Blk 40-52 Legacy Service Life Extension Program (SLEP): A two-phased RDT&E effort which includes Full Scale Durability Test (FSDT), and Engineering, Manufacturing and Development (EMD). FSDT required preliminary structural analysis, construction of a test fixture, and modification of an aircraft to begin testing. The FSDT contract awarded Apr 11 and aircraft cycle testing began Dec 12. FSDT is required to prove finite element models and to develop the airworthiness certification basis to extend the current Certified Service Life (CSL) from 8,000 Equivalent Flight Hours (EFH) to 10,000 EFH (Threshold), or 12,000 EFH (Objective). In accordance with the Aircraft Structural Integrity Program and MIL-STD 1530C, testing will support Blk 40-52 structural upgrade program that replaces or reworks known life-limited structure to preclude the onset of widespread fatigue damage, maintain safety of flight and enhance aircraft availability beyond 8,000 hours. FSDT is projected to complete cycle testing in Nov 14, with final recommendation in Nov 15. The Government will receive a re-procurement technical data package to support production and installs, maintenance Technical Orders, Time Compliance Technical Orders, manufacturing and installation tools, and all drawing packages necessary to sustain the SLEP modified aircraft through the extended certified service life. Production contract is planned to award in FY17, with FRP in FY19.
